Answer:
Nitrogen has an atomic number of 7; the neutral Nitrogen atom has 7 protons and 7 electrons. If Nitrogen gained three electrons it would have 10 electrons, like the Noble gas Neon (10 protons, 10 electrons). However, unlike Neon, the resulting Nitrogen ion would have a net charge of N3- (7 protons, 10 electrons).
Explanation:
I’m sorry but could you type the questions out? I can’t really see the question
Hence the resulting concentration of Li+ is 1M. Hope it helps.
The balanced chemical equation is:
<h3>2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + 4H₂O</h3>
Chemical equation can be balance by simply doing a head count of the different elements in the reactants and products to verified they are equal.
The equation given in the question above can be balanced as follow:
H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + H₂O
There are 2 atoms of SO₄ on the right side and 1 atom on the left side. It can be balance by writing 2 before H₂SO₄ as shown below:
2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + H₂O
There are a total of 8 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 4 before H₂O as shown below:
2H₂SO₄ + Pb(OH)₄ —> Pb(SO₄)₂ + 4H₂O
Thus, the equation is balanced.
